57923747 ÷ 421 
We want to divide 57923747 by 421.

Going ahead to step 1:
If we divide 5 by 421, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 421

Going ahead to step 2:
421 can be fit into 57 0 times, resulting in a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 421

Moving on to step 3:
421 goes into 579 1 times with a remainder of 158.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 421 from 579, we get 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 421

Step 4:
When dividing 1582 by 421, we get 3 with a remainder of 319.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1263 from 1582, we get 319.
Bring next digit (3) of the dividend behind the 319 and repeat the process: 3193 / 421

Step 5:
When dividing 3193 by 421, we get 7 with a remainder of 246.
Put 7 as the next digit of the answer. 
Result so far: 137.0
The remainder is 246 after subtracting 2947 from 3193.
Take the next digit (7) from the dividend and append it to 246, then repeat: 2467 / 421

Let's proceed to step 6:
If we divide 2467 by 421, we get 5 and a remainder of 362.
The number 5 becomes the next digit in our result. 
Result so far: 1375.0
If we take 2105 away from 2467, we end up with 362.
Fetch the next digit (4) from the dividend, attach it to 362 and continue: 3624 / 421

Let's proceed to step 7:
421 goes into 3624 8 times with a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 13758.0
Subtracting 3368 from 3624 leaves us with 256.
Append the next digit (7) from the dividend to 256 and continue with: 2567 / 421

Going ahead to step 8:
421 goes into 2567 6 times with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 137586.0
If we subtract 2526 from 2567, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
410 divided by 421 is 0 with a remainder of 410.
The number 0 becomes the next digit in our result. 
Result so far: 137586.0
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
If we divide 4100 by 421, we get 9 and a remainder of 311.
The next digit of our result is 9. 
Result so far: 137586.09
Subtract 3789 from 4100 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 11:
421 goes into 3110 7 times with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 137586.097
Subtracting 2947 from 3110 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 12:
421 goes into 1630 3 times with a remainder of 367.
Use 3 as the next digit of our solution. 
Result so far: 137586.0973
Subtracting 1263 from 1630 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 13:
The number 421 fits into 3670 8 times, leaving a remainder of 302.
The number 8 becomes the next digit in our result. 
Result so far: 137586.09738
Deduct 3368 from 3670 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 14:
When dividing 3020 by 421, we get 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 137586.097387
Deduct 2947 from 3020 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 15:
When dividing 730 by 421, we get 1 with a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 137586.0973871
Deduct 421 from 730 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 16:
421 goes into 3090 7 times with a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 137586.09738717
If we take 2947 away from 3090, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final outcome is 137586.09738717, with a leftover of 1.43e-07.
